Do you know why he's only around for a month during a year??Seems like maybe he is attracted but is holding back at the same time.Might be a "don't want to get too close" due to whatever set up is going on,one month out of a year isn't going to be a very good relationship in the long runAnd especially if you like him as much as your putting off here,you may be disappointed alot with that one month set up.
